Why Convert PPTX to PDF?

PowerPoint presentations rely on specific fonts and rendering engines installed on the viewer's machine, causing layouts to break and fonts to substitute for recipients without matching software.

Converting to PDF freezes every slide exactly as designed, making the deck reliably viewable on any device without PowerPoint.

Frequently Asked Questions

Will my custom fonts appear correctly in the PDF?
The browser converter uses standard fallback fonts. Custom fonts not available in the browser are substituted. TeraConvert Desktop uses LibreOffice with your system's installed fonts for accurate rendering.
Are speaker notes included in the PDF?
The standard conversion renders slides only, without speaker notes. TeraConvert Desktop's LibreOffice conversion preserves speaker note pages as an appendix when configured.
Will animations and slide transitions appear in the PDF?
PDF is a static format. Animations and transitions are rendered as static frames showing the final state of each element.
How many slides can the browser converter handle?
The browser handles most standard presentation sizes under 25 MB. For large presentations with embedded videos or many high-resolution images, TeraConvert Desktop handles files of any size.
Is this conversion really free, and is my file private?
Yes. The browser conversion runs entirely on your device using WebAssembly. Files are never uploaded to a server and are discarded from memory when you close the page. There is no file size tracking, no account link to your upload, and no cloud storage.
Do I need to create an account to convert files?
No. The browser converter works without signing in. An optional account is only needed if you want to save favorites, track conversion history, or upgrade to the desktop app with Polar license activation.
How fast is the conversion?
Most browser conversions complete in a few seconds. Large files (over 100 MB) or heavy formats (video, high-page PDFs) take longer depending on your device's CPU and available memory. The desktop app runs significantly faster using native engines.
